When wrapped up in packaging, hidden from the world, it is hard to tell exactly what a Subway sandwich is packing.

But an Australian sleuth with a measuring tape has whipped up a firestorm of controversy after he discovered the sandwich-maker’s dirty little secret — Subway’s famous “footlong” sub measures in at a measly 11 inches.

Matt Corby posted an incriminating picture of his favorite “footlong” next to a measuring tape with the caption “subway pls respond” on the company’s Facebook page yesterday and it already has over 100,000 likes and has sparked a slew of copycat postings demanding an explanation.

While the company hasn’t commented on the controversy yet, one popular online explanation for the sub’s small size is that a toasted sub shrinks while a cold one maintains it’s full length.

However, Facebook commenter Scott Blair didn’t agree with this explanation saying, “Just got out of the pool and it was cold, Don’t judge!!!”
